Creating the next Gundam series in ten steps by that creepy Destiny fan with bizarre opinions (

):
1. Get Go Nagai and Masami Obari on staff/involved in the story and mech designs; Obari and Kunio Okawara work together to make the titular gundam.
2. Get JAM Project for some awesome soundtracks.
3. Get Yoko Kanno and/or Maaya Sakamoto to fill in what JAM Project can't music wise.
4. Have a cast like Brave Command Dagwon: Everyone gets a mobile suit save for the captain and bridge crew and the main character gets the gundam. In part of this bring back classic non-gundam protag suits like Guncannon, Guntank, Hyaku Shiki, Methuss, Kapool, Moebius Zero, ZAKUs, GN Archer, etc.
5. Love interest also pilots a mobile suit; either have no romance at all or build it up enough to when it actually does there is pay off at the very end (like the main protag getting a lip kiss or getting some off screen).
6. Two main villains that consist of a fleshed out Char clone and his incredibly evil/total monster master. After some betrayal late in the series the Char clones joins the good guys and takes on the big bad in a super high performance mobile suit that lasts the entire last episode. At the height of the climax use either an opening theme or Ode to Joy.
7. No useless children.
8. No pointless fan service, not even a loyalty bonus.
9.
An enemy with understandable motives and sympathetic soldiers who don't commit atrocities for no reason.

and 10. No epilogues. Seriously, save for X no series ever made a good/fitting one, so just don't have one at all.
